Check out this documentary that follows the filmmaker’s journey from overweight, heavy-drinking, asthmatic smoker to (almost) elite athlete in just two years. It’s available to watch in three parts on YouTube and is very inspiring. (About 40 minutes total).
Thanks to Matt Slater for suggesting I watch this!
